YARN STRIPPER.

Application filed January 25, 1924. Serial No. 688,595.

To all whom it may concern:

Be it known that I, JAMES D. JOYCE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Yarn Strippers, of which the following is a specification.

This invention relates to yarn or thread cleaners for use on winding machines and is an improvement on my yarn and thread cleaner disclosed in Patent Number 1,431,- 812, granted October 10, 1922.

In the device shown in the patent, above referred to, no provision is made for relatively adjusting the stripping members so that their axes, and hence their working surfaces shall be parallel throughout their lengths.

It is the object of this invention to provide means for aligning the stripping members of my earlier device.

Other objects of my invention will appear in the accompanying specification and claims and will be disclosed in the accompanying drawings in which Figure 1 is a perspective view in detail of the parts of my device in position to be assembled;

Figure 2 is a side elevation of my device;

Figure 3 is a bottom plan view of my device;

Figure 4 is a section on line 4-4 of Figure 2.

Referring with greater particularity to the drawings it will be seen that my device is comprised as follows:

The bracket 1 has the usual flange 2 provided with screw holes 3 for attaching the same in operating position; the lateral lug 4 to provide for the mounting of the guide finger 5; the usual four edged blade 6, channelled bar 7 and cylindrical glass stem 8.

The head 9 of my new device has an extended portion which is split at 11 into two jaws 12 and 13 between which, in the opposed substantially semicircular grooves 14 and 15, the blade is adapted to be mounted and clamped into position by set screw 16.

The head 9 has an arm 17 extending substantially at right angles to the bracket. The arm 17 has a bore 18 threaded to receive a screw bolt 19 on which the channelled bar 7 is pivotally secured by means of arm 7*. The stem 8 is securely held fixed in position in the channelled arm 7.

The arm 17 is further provided with two vertically extending screw threaded bores 20 and 21, to receive set screws 22 and 23 adapted to extend upwardly through the arm 17 and bear against'the base'of'the channelled bar 7. The blade 6 is provided with apertures 24 for the insertion'of a tool for adjustably rotating the blade around its longitudinal axis.

My device havin been described in detail its operation will The blade 6 is first adjusted to the position desired with relation to the stem 8, theposition depending largely upon the size and type of yarn being wound. The arm 7, and

hence the stem 8 is then turned around its pivot 19 by means of set screws 22 and 23 until the surface of the stem is parallel to the cutter blade. The stem and the blade will then be separated, throughout their lengths, by a space of uniform Width. If

it is desired, for any reason, to make this e seen to be as follows:

smooth surfaced stem pivotally secured to said arm.

2. In combination, in a yarn or thread stripper for winding machines, a bracket, a laterally extending blade so mounted in said bracket as to permit adjustment around its longitudinal axis, a laterally extending arm on said bracket, and a filament supporting smooth surfaced stem pivotally secured intermediate of its ends to said arm.

3. In combination, in a yarn or thread stripper for winding machines, a bracket, a laterally extending blade so mounted in said bracket as to permit adjustment around its longitudinal axis, a laterally extending arm on said bracket, a filament supporting smooth surfaced stem pivotally secured intermediate of its ends to said arm, and

means for pivotally adjusting said stem.*

4. In a yarn or thread stripper for winding machines, the combination with a bracket of a laterally extending filament supporting arm having a smooth surface, an arm angular in cross section having a plurality of cutting edges adjustably carried substantially parallel to the supporting arm forming an open space between same and the supporting arm the width of which space may be varied by the adjustment of the cuttingarm, the filament supporting arm being pivotally adjustable to maintain parallelism of the two said arms.

5. In a yarn or thread stripper, the combination. with a bracket, of a laterally extending filament-supporting arm having a smooth surface, an, arm; rectangular in cross section having a plurality of cutting edges mounted, parallel to the supporting arm forming an open space between same and the supporting arm, and means for adjusting the cutting arm with relation to the supporting arm whereby the space between same may be changed and the several cutting brought into alternate operative relation to the supporting arm, the filament supporting arm being pivotally adjustable to maintain parallelism of the two said arms.

In testimony whereof ll afhx my signature.

JAMES D. JOYCE.
